Florida Man Posts Picture of His Dead Wife on Facebook

MIAMI (AP) - A home surveillance video shows a man accused of killing his wife and then posting a picture of her bloody body on Facebook walk away from a confrontation and then return moments later to fire a gun.

The weapon can't be seen in the video released Tuesday by the Miami-Dade State Attorney's Office to The Miami Herald (http://goo.gl/hThSbq). But the surveillance camera did pick up the swirl of gunpowder in the air from when authorities say 31-year-old Derek Medina fatally shot 26-year-old Jennifer Alfonso at their South Miami home on Aug. 8.

The footage also shows Medina calmly retrieving a jacket and his phone, apparently stopping to take a photo of Alfonso's body and then walking out of the townhome.

Medina has claimed that his wife was the aggressor and that he was acting in self-defense.
